what colour is this ?

[paddy]

Any idea what this colour is on the engine cases. I come across it a lot on bikes and cars, it looks like a king of graphite maybe ?? Often see it on raw dark alloy castings like gearboxes.

This is my weakness...no clue.

You stated a color that seems to match... Graphite. My solitary opinion, of course!
